Title:
CONVEYOR DEVICE FOR SHEET RECORDING MATERIAL AND IMAGE RECORDING DEVICE
Document Type and Number:
Japanese Patent JP2005089058
Kind Code:
A
Abstract:

To correct a gap of timings for a conveyer roller pair to grip and release a record material.

The conveyer roller pairs 30, 31 are composed of capstan rollers 33, 35 and nip rollers 34, 36 respectively. The nip rollers 34, 36 can move between a gripping position and a releasing position. A pair of position sensors 63, 64 are arranged along conveyer route of a recording sheet 24. The nip roller 36 on a downstream side is moved toward the nipping position at a time T2 after a position sensor 64 on the downstream side detects a leading end of the recording sheet 24. The nip roller 36 on an upstream side is moved toward the release position at a time T3 after a position sensor 63 on the upstream side detects a trailing end of the recording sheet 24. A plurality of test prints 100 is formed with different values of T2 and T3. T2 and T3 are changed by observing a pattern on the test prints 100 and selecting optimum test print number.
